believe the concern is the transfer of heat between different materials. I can’t
remember where I saw it, but there was a table showing the transferring heat
between base and finish materials, say tile to concrete slab below in passive
solar conditions and the rate of transfer was much less than one might think.
The joint between the two impeded the heat transfer, in other words. I would
think an acrylic additive may impede the transfer even more. The best is always
to not cover the slab, only color it, if heat retention in the slab is the
goal.<o:p></o:p></SPAN></P>

<P class=MsoNormal><BR>A concrete overlay product is likely to be roughly
similar in thermal characteristics to a concrete slab. Meaning that you
will just have a thicker thermal mass. It seems unlikely that you should
be worried about <I>too much</I> thermal mass in a passive solar house.
The overlay product might have a lower specific heat, or conductivity, wither of
which will reduce it's effectiveness somewhat. Remember to stick with a
dark color.<BR><BR>Thank You Kindly,<BR><BR>Corwyn<BR><BR><o:p></o:p></P><PRE>-- <o:p></o:p></PRE><PRE>Topher Belknap<o:p></o:p></PRE><PRE>Green Fret Consulting<o:p></o:p></PRE><PRE>Kermit didn't know the half of it...<o:p></o:p></PRE><PRE><A href="http://www.GreenFret.com/">http://www.GreenFret.com/</A><o:p></o:p></PRE><PRE><A href="mailto:topher@greenfret.com">topher@greenfret.com</A><o:p></o:p></PRE></DIV>
